Linear 212SE Weather-Resistant Keypad

The Linear 212SE is a weather‑resistant, surface‑mount access control keypad designed for both indoor and outdoor use, built in a seamless brushed‑metal housing treated to resist corrosion. It supports up to 120 user codes, with a rugged metal Braille alphanumeric keypad for durability in all conditions. An internal sounder provides feedback on key presses, complemented by a bi‑color LED for clear operational indication. The housing installs directly onto a standard single‑gang electrical box or other flat surfaces—ideal for wall, post, or gooseneck mounting. It features four onboard programmable timed relays and supports tamper‑loop functionality in 212 or 232 modes for increased security. The unit is self‑contained, vandal‑resistant, and operates on 12–24 VAC or VDC with auto‑adjustment. Current draw is 108 mA (plus 30 mA per additional relay). It operates reliably within a wide temperature range from −20 °F to 130 °F, making it highly suited for demanding access control environments.
